BACKGROUND OF THE INVENTION

The present invention relates to hunting decoys and in particular to agame bird decoy that provides more natural movement.

Decoys for bird hunting may include very simple silhouette decoys whichprovide two-dimensional representations of a bird in silhouette andshell decoys which provide static, three-dimensional representations ofa full-bodied bird. The latter shell decoys are preferable to silhouettedecoys to the extent that they present a better simulation of a birdfrom a circling flock overhead.

More advanced decoys also provide for motion. Decoys of this type mayrely on wind to move the decoy or decoy parts or battery-powered motorswhich provide for oscillating or rotating decoy parts. While it isgenerally appreciated that adding motion to a decoy can improve itsrealism, poorly implemented motion can have the opposite effect,creating a decoy whose unnatural motion is more frightening than astatic decoy and that causes passing flocks to be startled or flarebefore they approach.

SUMMARY OF THE INVENTION

The present invention provides a moving decoy that better captures thenatural motion of a goose or similar game bird in critical aspects, mostnotably, the characteristic, highly flexible goose neck. The inventionfurther may coordinate neck orientation with posture and wing movementwith change in posture. The decoy may be actuated by remote control orby automatic scripts allowing the motion to vary as would occur with thenatural goose. In one mode of operation, multiple decoys makeintercommunication to provide for flock-like behavior in which activityripples through multiple decoys in the manner of actual birds respondingto one another.

In one embodiment, the invention provides game bird decoy having a bodyelement with a flexible neck element extending therefrom, the bodyelement and flexible neck element sized and decorated to resemble anatural bird. The flexible neck element may include a stack ofinter-engaging neck segments extending along a neck axis, each necksegment pivotally attached to an adjacent neck segment to provide alimited pivoting with respect to the adjacent neck segment to curve theneck axis. At least one restoring spring urges the neck segments intoresting alignment, and at least one tension band is attached to an upperneck segment to extend downwardly along the neck segments to follow anycurvature of the neck axis where it is attached to a servo-motorapplying tension to the tension band to controllably curve the flexibleneck element. An electronic computer executes a stored program tocontrol the servo-motor to provide for controlled bending of the neckaxis.

It is thus a feature of at least one embodiment of the invention tointroduce a motion element to otherwise static decoys closer matchingthe natural movement of the goose or similar game bird.

The game bird decoy may include at least three tension bands attached toat least two servo-motors to provide for forward and left and rightcontrolled curvature of the flexible neck element.

It is thus a feature of at least one embodiment of the invention topermit complex articulation of the neck, for example, simulating feedingor preening by the bird.

The restoring spring may be a central spring element passing upwardthrough the inter-engaging neck segments and wherein the restingalignment is a substantially straight alignment of the inter-engagingneck segments.

It is thus a feature of at least one embodiment of the invention toprovide a simple and robust spring-return element of eliminating theassembly of multiple parts or the use of elastomeric materials that maydegrade between seasons.

The game bird decoy may include a head element rotatably attached at adistal end of the neck element to rotate about the neck axis as actuatedby a servo-motor, and/or the head element may be mounted to the neckelement to allow bobbing of the head element with respect to the neckaxis about an axis perpendicular to the neck axis as actuated by aservo-motor.

It is thus a feature of at least one embodiment of the invention toprovide improved articulation of the head thought to be an importantelement for simulating lifelike motion.

The head element may further include a hinged jaw element movablebetween a closed position when the head is upright and an open positionwhen the head is vertically inclined.

It is thus a feature of at least one embodiment of the invention toincorporate lifelike mouth movement into the head.

The neck segments may include plate elements having holes at theirperipheries receiving the tension bands to provide ball jointscommunicating with at least one adjacent neck segment.

It is this a feature of at least one embodiment of the invention tomimic the actual vertebrae of an elongate neck with a simple mechanicalelement to better simulate natural motion.

The game bird decoy may include a leg stand adapted to support the gamebird decoy on a level surface, the leg stand pivotally attached to thebody element to allow the body element to tip upward about a horizontalaxis with respect to the leg stand as actuated by a body servo-motor.

It is thus a feature of at least one embodiment of the invention toallow for a craning movement found in natural geese and the like.

The neck element may be pivotally attached to the body element and alinkage may communicate between the leg stand and the neck element tochange an angle of attachment between the body element and the neckelement to provide a substantially constant angle of the neck elementwith respect to the leg stand as the body element tips upward.

It is thus a feature of at least one embodiment of the invention tomimic the natural stabilization of the head during body motionimplemented by living creatures.

The linkage may provide a set of pivoting rigid link elements wherein atleast one link element is captured along its length by a collar fixedwith respect to the body element for constraining motion of the linkelement perpendicular to an extent of the link element.

It is thus a feature of at least one embodiment of the invention toprovide a simple linkage that may effect a complex positional adjustmentnormally requiring control of multiple tissue structures.

The game bird decoy may further include at least one wing strutpivotally attached to the body element at a shoulder position proximateto the neck element and extending therefrom and actuable by a wingservo-motor.

It is thus a feature of at least one embodiment of the invention toprovide for wing motion normally attendant to balancing the body duringmovement of the body.

The game bird decoy may include a wing control strut attached to thewing strut and operable by at least two servo-motors to independentlyoperate in a first mode to elevate the wing strut without substantiallateral extension and in a second mode to elevate and laterally extendthe wing strut.

It is thus a feature of at least one embodiment of the invention toprovide multiple nuanced wing motions to produce a richer vocabulary ofanimation better matching actual game bird behavior.

The wing control strut may cooperate with the body servo-motor toelevate and laterally extend the wing strut in the second mode when thebody is tipped upward.

It is thus a feature of at least one embodiment of the invention tomimic the natural wing adjustment that occurs when the bird is tippingits body upward.

The wing strut may include a humerus section pivotally attached to thebody element, an ulna section pivotally attached to the humerus sectionand a metacarpus section pivotally attached to the ulna section, eachthreaded with an interconnecting tension cord operating to extend thesections with respect to each other to more closely approximate a singleline when the tension cord is pulled, and wherein operation of the bodyservo-motor to tip the body upward operates to tension the tension cordto straighten the wing strut in addition to elevating and laterallyextending the wing strut.

It is thus a feature of at least one embodiment of the invention toprovide a more anatomically correct wing motion reflecting the multiplewing bones of the bird.

These particular objects and advantages may apply to only someembodiments falling within the claims and thus do not define the scopeof the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to FIG. 1, a kinematically realistic goose decoy 10 mayinclude a body section 12 supported by a leg stand 14 extending downwardtherefrom. The body section 12 further has a neck section 16 attached atthe front of the body section 12 extending generally upward therefrom toa decoy head element 18. Wing elements 19 maybe attached on either sideof the body section 12 to move independently of the body section 12.Each of the leg stand 14, body section 12, neck section 16, head element18 and wing elements are covered with a flexible covering such as acloth or foam material and are sized, positioned and decorated to looklike corresponding elements of an actual goose.

As will be discussed in greater detail below, the goose decoy 10 mayprovide for a range of different servo-motor controlled motions. As willbe understood in the art, servo-motors provide for position control ofan actuation lever attached to the motor, the position control obtainedthrough the use of an internal or external feedback loop comprising aposition sensor such as a potentiometer and a DC permanent magnetgearmotor or the like.

In a first motion, the body section 12 may tip upward with respect tothe leg stand 14 as indicated by arrow 20. Additional motions allowcurvature of a neck axis 22 of the neck section 16 to bend forward asindicated by arrow 24 in the manner of goose neck providing a generallycurved continuous bending as will be discussed below. The wing elements19 may elevate vertically as indicated by arrow 26. The head element 18may nod along a vertical axis with respect to the neck section 16 asindicated by arrow 25.

Referring now to FIG. 2, wing elements 19 may also extend laterally asindicated by arrows 27. The head element 18 may pivot about the neckaxis 22 as indicated by arrows 28, and the neck axis 22 of the necksection 16 may curve left or right also providing for a smoothcontinuous curving in that motion as indicated by arrows 30.

Referring now to FIG. 3, the head element 18 may provide for an internalarmature 32 attached to an upper vertebral segment 62 of the necksection 16 by means of a swivel joint 36 allowing the armature 32 torotate as shown by arrows 28 about the neck axis 22.

Referring momentarily to FIG. 5, a servo-motor 38 attached to one halfof the swivel joint 36 may move a linkage 40 communicating with astructure attached to the other half of the swivel joint 36 so thatmotion of the servo-motor 38 provides for swiveling of the head armature32.

Referring again to FIG. 3, head armature 32 may provide for anupstanding yoke 42 that supports a head frame 44 to pivot about ahorizontally extending pivot pin 46 to provide the nodding action ofarrow 25 shown in FIG. 1. A servo-motor 48 attached to the yoke 42communicates with the head frame 44 by a linkage 50 to provide aservo-actuated control of the nodding action of arrow 25.

Attached to the head frame 44 which extends into the beak area of thehead element 18 is a lower beak 52 that may freely pivot abouthorizontal hinge pin 54 with respect to the head frame 44. Acounterweight 58 opposite the hinge pin 54 from the lower beak 52 holdsthe lower beak 52 into a closed position against an undersurface of thehead frame 44. Referring now also to FIG. 4, when the head frame 44 istipped downward (for example, by articulation of the neck section 16 aswill be discussed below) the counterweight 58 passes over the hinge pin54 causing a clockwise rotation of the lower beak 52 as shown in FIG. 4opening the lower beak 52 to simulate a goose opening its mouth to feedon an object near the ground.

The lower beak 52 may extend through a flexible covering 60 whichotherwise covers the yoke 42, head frame 44, and servo-motors 38 and 48.

Referring now to FIGS. 6 and 7, the lower half of the swivel joint 36may attach to an upper vertebral segment 62 a being one of six vertebralsegments 62 a-f that are stacked to provide the neck section 16. Eachvertebral segment 62 provides a generally cylindrical disc having acentral bore 64 with opposed concave depressions sized to provide asocket receiving intervening balls 63 between pairs of vertebral segment62. The ball 63 and the vertebral segment 62 when oriented verticallyalong a straight vertical neck axis 22 provide a continuous centralpassage through each of the vertebral segments 62 through which ahelical spring 67 may be inserted, the helical spring 67 providing abiasing force on the vertebral segment 62 tending to straighten thestack of vertebral segments 62 and balls 63 along a vertical neck axis22.

Each of the vertebral segments 62 may further have axially directedholes 65 in peripheral regions of the vertebral segment 62 for receivingtension bands 66 there through. Specifically left and right holes 65 aand 65 b are diametrically opposed across the bore 64 and may receiveleft and right vertically extending tension bands 66 a and 66 bthreading successively through each vertebral segment 62. Similarly, aset of axial holes 65 toward the front of the vertebral segments 62 andequally spaced from left and right holes 65 a and 65 b receive a fronttension band 66 c. The tension bands 66 pass freely through the holes 65of all but the uppermost vertebral segment 62 a where they are anchoredat anchor points 69 on the upper face of the vertebral segment 62 a.

The lower ends of the left and right tension bands 66 a and 66 b arereceived by opposite ends of a servo-motor lever 68 actuated at itscenter by servo-motor 70. It will be appreciated that motion of thelever 68 in respective clockwise and counterclockwise directions (asdictated) will cause a smoothly curved articulation of the stack ofvertebral segments 62, right and left, in the manner of a gooseneck. Inthis motion, the angulation of each vertebral segment 62 with respect toits neighbors is substantially equal as moderated by the restoring forceof the internal spring 67, the angulation of the vertebral segments 62operating to reduce the energy of the deformation of that spring 67.

A separate servo-motor 72 positioned near servo-motor 70 provides alever 75 connected to the lower end of front tension band 66 c toprovide a forward bending of the neck section 16 downward, for example,as if the goose were feeding, when lever 75 is moved downward. Thismotion of the neck section 16 may activate the lower beak 52 shown inFIG. 3.

Referring now to FIGS. 8 and 9, the lower vertebral segment 62 f may beattached to a movable platform 71 also holding the servo-motors 70 and75 and attached to an internal frame structure 76 of the body section 12by horizontal pivot pin 77. A lever 79 may extend rearwardly from themovable platform 71 past the pivot pin 77 to be connected by linkageelements 78 a and 78 b in the internal frame structure 76. Linkageelements 78 a and 78 b connect the lever 79 to anchor pivot 80 fixedwith respect to the leg stand 14. The linkage elements 78 a and 78 b arepivotally attached to each other and to the respective lever 79 andanchor pivot 80. A central portion of the linkage element 78 b isrestrained by a loosely fitting collar 81 fixed relative to the framestructure 76. As shown in FIG. 10, the collar 81 allows sliding of thelinkage element 78 b through the collar 81 as well as a rocking orpivoting about the collar 81 but largely resists motion of the linkageelement 78 b perpendicular to its length.

The leg stand 14 may be attached by hinge element 82 to the framestructure 76 so that, as shown in FIG. 9, the frame structure 76 may tipupward about a horizontal axis as if the goose were changing its bodyposture. With this upward tipping, the pivot pin 77 rises as well as theplatform 71 lifting the neck section 16. At the same time, operation ofthe linkage elements 78 serve to rotate the platform 71 clockwiseslightly in compensating motion to preserve its level aspect withrespect to the ground on which the leg stand 14 rests. In this way theorientation of the neck section 16 is isolated from changes inorientation of the body section 12 in the manner of an actual goose.

Tipping of the frame structure 76 upward with respect to the leg stand14 may be accomplished by a servo-motor 84 communicating with a backbonestrut 88 forming part of the frame structure 76, the servo-motor 84fixed to a structure stationary with respect the leg stand 14. In thisway the tipping of the body section 12 may be flexibly controlled toactuation of the servo-motor 84.

Referring now to FIGS. 11 and 12, the back backbone strut 88 may supportat its front edge a shoulder platform 89 at approximately a locationwhere a bird's wings would connect to the body. The shoulder platform 89provides two outwardly facing (left and right) ball joints 90 a and 90 battached in turn to wing struts 92 a and 92 b shown passing rearwardalong the body section 12 and providing an internal support structurefor decoy wing elements 19 (shown in FIGS. 1 and 2).

Control struts 94 a and 94 b are attached at one end via pivot joints 96to respective wing struts 92 a and 92 b at a position removed from theball joints 90 and slightly rearward therefrom. A midsection of eachcontrol strut 94 is supported by respective pivot joints 98 on a slider100, the latter of which may slide along the backbone strut 88 as willbe discussed below. The pivot joints 98 allow multidimensional pivotingof the respective control struts 94 without sliding of the controlstruts 94 therethrough.

The control struts 94, after being received by the pivot joint 98,extend rearward therefrom crossing over the slider 100 and the backbonestrut 88 to terminate at cantilevered points connected to a chain 102that passes downward on either side of the backbone strut 88 to bereceived by a lever 104 of servo-motor 106.

It will be appreciated that activation of the servo-motor 106 moveslever 104 in a counterclockwise direction pulling down on the chain 102and the attached ends of the control struts 94 to raise the attachedwing strut 92 providing a vertical elevation of the wing without wingextension as indicated by arrow 26 in FIG. 12. In contrast, movement ofthe slider 100 forward serves to simultaneously extend the wing struts92 outward as indicated by arrows 27 caused by movement of the pivotjoint 98 forward and to elevate the wings per arrow 26 caused byincreased tension in the chain 102, without needed movement of theservo-motor 106. In this way, two different types of wing motion can beobtained.

Referring also to FIGS. 8 and 9, movement of the slider 100 may occurautomatically upon tilting upward of the body section 12, for example,as shown between FIGS. 8 and 9, such as causes a slide weight 112slidably mounted to the backbone strut 88 to slide rearward. A cable 114passes forward from the slide weight 112 through a front mounted pulley116 near the platform 89 and then backwards to connect with the slider100 so that rearward motion of the slide weight 112 serves to pull theslider 100 forward. In this way, elevation of the body section 12 asshown in FIG. 9 causes an extension of the wings simulating a balancingthat might be performed by a natural bird when craning its neck.

The slide weight 112, in one embodiment, may hold lithium ion batteriesused for powering of the servo-motor system ascribed herein.

Referring now to FIG. 13, in an alternative embodiment, the wing strut92′ may comprise multiple hingedly-connected segments including an ulnasection 120 attached between ball joint 90 b and a first pivot joint 122communicating with a humerus section 124. The humerus section 124 may inturn, communicate through pivot joint 126 to a metacarpus section 128.The sections 120, 124, and 128 correspond generally to the same bonesfound in a bird's wing and have similar proportions.

Referring to FIG. 14, each joint 122 and 126 may include a tension bandguide 130, for example, providing a pulley wheel coaxial with the jointaxis 132 and a torsion spring 134 for biasing the joint in a particulardirection. A similar arrangement may be applied to ball joint 90 b withthe springs 134 operating so as to generally fold ulna section 120rearward the against the body section 12 and fold the humerus section124 forward and the metacarpus section 128 backward in a compactarrangement. A tension band 136 may be anchored to a distal end of themetacarpus section 128 and may pass around and outside of each of thetension band guides 130 associated with the joints 126, 122 and 90 b tobe received by a pulley 142 at which it may curve along the backbonestrut 88 to attach to the slide weight 112. It will be appreciated thattension on the tension band 136 will thus serve to elongate the wing togenerally pull each of the ulna section 120, humerus section 124, andmetacarpus section 128 into a mutually straightened alignment laterallyextending from the body. In this way the wings may extend more naturallywhen the bird body section 12 tips upward as shown in FIG. 9.

Referring now to FIG. 15, each of the servo-motors 38, 48, 70, 72, 84,and 106 may be controlled by a microcontroller 150 having a processor152 communicating with a memory 154 holding a stored program 156 as willbe described below. The microcontroller 150 may communicate with a radiotransceiver 160 that may communicate with a corresponding remote controlunit 165 of the type used with remote-controlled aircraft having atransmitter 163 associated with a remote control keypad 164 or with asmart phone 166 or similar device and with the transceivers 160 of othergoose decoys 10. The body section 12 may contain lithium ion batteries162 to provide power for each of the components.

Program 156 may provide for the decoding of signals from the remotecontrol unit 165 allowing continuous control of each of the servos forhighly accurate and precise manipulation of the elements describedabove. In addition or alternatively the program 156 may hold motionscripts that may be invoked to produce various sequences of motionautomatically according to a time schedule and list of motions stored inmemory 154.

Referring now to FIGS. 16 and 17, in one embodiment, multiple goosedecoys 10 a and 10 b (only two shown for clarity) may be deployedtogether to automatically produce a flock-like motion in whichstimulation reflected in motion by one goose decoy 10 a ripples throughthe remainder of the flock in the manner of actual flock of birds. Thus,for example, goose decoy 10 a may be triggered to execute a script bythe remote control unit 165, for example, to elevate the body section 12and then the head element 18 and raise the wings elements 119. Thiscommand is indicated by process block 170. After the script is executedas indicated by process block 172, a delay may be imposed and a commandsent from goose decoy 10 a to a next goose decoy 10 b per process block176 (for example, according to address order or programmed order) sothat goose decoy 10 b executes the same script or an analog of thatscript providing a mimicking behavior.

In this regard, it is contemplated that some goose decoys 10 will havelimited functionality and accordingly will execute a modified script ifall mechanisms necessary for the script execution cannot be implemented.For example, some goose decoys 10 may provide for only wing articulationand some decoys may provide for only neck articulation. In this regardeach of the goose decoys 10 may be modular to allow additionalmechanical structures to be added to the decoys after purchase, forexample, to improve their functionality. It will be appreciated that thepresent invention is not limited to geese but that all or portions ofthe present invention may be used in constructing decoys for other gamebirds including but not limited to other geese such as snow, brant,speckle bellied and blue geese as well as ducks including mallard, wood,green and blue wing teal and numerous other duck species and other birdssuch as cranes and swans.
